HYDROCARBON BURNER.

Application filed April 27, 1927.

My invention has for its object to provide an eflicient hydrocarbon burner which is so constructed that it will gasify the fuel at a very high temperature and maintain the fuel in an attenuated state within the burner while it is being mixed with air under pressure. The invention also provides for the addition of air at a high temperature whereby a perfect combustion is brought about. Burners containing my invention are also so constructed that owing to the high temperature at which the hydrocarbon is subjected to, a water gas may be formed by causing a mixture of and reaction with steam which is introduced in the heated hydrocarbon.

The invention may be contained in structures of diiferent forms and to illustrate a practical application of the invention, I have selected two forms of burners illustrating embodiments of my invention and shall de scribe them hereinafter. The constructions selected as examples are shown in the accompap ying drawings.

1g. 1 illustrates a side view of one form of burner. Fig. 2 is a top view of the device illustrated in Fig. 1. Fig. 3 is a view of a section taken on the plane of the line 3-3 indicated in Fig. 1. Fig. 1 is a side view of the other form of burner selected as an example. Fig. 5 is a top view'of the burner shown in Fig. 4.

In the particular constructions shown in the drawing, the burners are provided with a hemispherical bowl into which the hydrocarbon, in the form of oil, is introduced, and a tip, or nozzle, communicating with the bowl is directed towards the bowl which produces a flame that covers the top of the bowl in the form of an inverted mushroom. In the form of burner shown in Fig. 1 a hemispherical bowl 1 is connected to a suitable source or supply of oil by means of a pipe 2 that is threaded into an opening formed in the bottom of the bowl. A pipe 3, made in the form of a goose neck and, preferably, cast integral with the bowl, extends upwards from one side of the bowl and over the top of the bowl. A passage-way 4 of the pipe 3 leads from one side of the bowl chamber, as indicated in dotted lines in Fig. 1. The interior and the exterior diameters of the pipe 3 are substantially as shown in Fig. 1. The bottom of the interior of the pipe 3 has communicating therewith an opening 5 of very the air enters.

small bore and a pipe 6 communicates through this passage-way with the pipe 3. The pipe 6 may be connected with a source oi air under pressure in order to force air at a very rapid rate of movement through the opening 5 into the pipe 3. The pipe 3 being located at one side of the chamber of the hemispherical bowl 1, the movement of the air through the passage-way 5 increases the rate of movement of the gas from the bowl and at the same time produces a thorough mixture of the air with the gas in the pipe 3. This causes both the air and gas to thoroughly mix and to move towards the outlet at the upper end of the pipe 3. The pipe three terminates in a spherical head 10 that has a relatively large spherical cham ber 11. An opening is provided in the lower part of the head 10 and a threaded sleeve 12 is threaded into the opening. The upper end of the sleeve 12 is tapered as at 13 and is provided with a small opening 14, through which the mixture of air and gas passes with considerable velocity, and a nozzle, or tip, 15 is threaded onto the sleeve 12. The nozzle 15 is, preferably, in the form of an inverted frustum and is provided with the openings 16 in its upper end through which The air is drawn into the nozzle 15 by the moving mixture of air and gas as it leaves the head 10. The nozzle 15 terminates with a short cylindrical end 17 which forms the outlet of the mixture of gases. The sleeve 12 extends well within the nozzle 15 and in the region of the cylindrical portion of the nozzle which produces a Venturi action. This produces a rapid movement of the gases, namely, the auxiliary air through the opening 16 and the mixture of air and gas from the head 10 of the pipe If the gases are ignited, the flame is directed towards the top of the bowl 1 and spreads over the surface of the top in the form of an inverted mushroom, or toadstool, which raises the bowl 1 to a very high temperature and maintains it at all times. Furthermore, the tip, or nozzle, of the burnor being located above the flame the gases that pass through the pipe 3 and the head 10 are also maintained at a very high temperature and the air that enters through the openings 16 is highly heated.

The top of the bowl 1 is, preferably, formed sloping, which slopes the interior upper surface of the bowl towards the passage-way 4: of the pipe 3. Preferably, the top of the bowl is provided with a ridge which slopes towards opposite edges ot the bowl. The ridge 2t) extends diametrically from the edge of the bowl to the pipe 3.

If desired steam may be introduced through the pipe 6 when the temperature of the gaees within the bowl has been raised to a. very high point. This will cause the desired rapid movement of the gas and if the teniperatures are raised to a sutliciently high point, a form of water gas may be produced.

In the operation of the burner the bowl 1 may be tilled with oil and as the flame inttnisiiies in heat the .surlace of the oil will be forced bacl; by pressure ot the gas that is created by the heat. But; as the gasiticd oil tFtftlptJh' new oil will be continuously led into the howl and r-l1l)jttt(ti to the intensity of the heat produced by the flame. The gusts will raise. to the sloping surface of the top ot' the bowl and be more intcn -ely heated when they will escape through the pipe ii and their movement acc ntuated by the injection of the air or .steam through the narrow passage-way 5. Auxiliary air will be drawn through the opening 16 and mixed in the 'r'enturi shaped nozzle as the gas passes through the throat of the nozzle and so a+ to produce. a. pertcct comlun-tion as the gases are carried down to the top of the bowl 1..

In order to start. the burner a combustible liquid may be. inserted in the trough 2L which surrounds the sides of the hemixpherical bowl t.

In the form of burner shown in Figs. t and 5, a plurality of nozzles 15 are supported on the heads 1t) ol the pipca 525 that are aleo arranged ('ireumlercnt-ially around the. edge ol the bowl in. The interior pas- -agt--way ol the pipes :25 communicate with the interior of the howl 226, the pipes being located so that the axee ol the pipes 25 will be located substantially in line with the small openings 27, which communicate with the pipe 28. The pipe 28 may be connected with the source of air under preseure. The arrangement is such that the same conditimr; are produced which the outlets of the nozzles 17 will produce in the form of construction shown in Fig. 1.

The top of the hemispherical bowl "it; may be provided with a central cone portion 29 thattLl'lIllDtllOS in a pipe 30. A pipe 11 ex tends into the pipe lit). The pipe 31 may be connected with the source of supply of steam. The. nozzleb 1,5 are F0 located 215 to direct the flame that is formed towards the cone 29 and raise the gases within the cone to a very high temperattu'e. The gases will rise through the pipe 30 and the steam which passes through the pipe 3]. will mix with the gases producing a :l'orn'i of water gas which may be drawn oil from the pipe 30.

The lower end of the bowl it, is provid d with a connector 32 through which the pipe Iji extends and which i.--: connected to the pipe 33 .hrough which oil may be directed into the bowl 2a. The operation of the burner :zhown in Ft 4- and 5 is substantially the. same as that of the operation of the burner shown in Fig. 1. except that, the steam is introduced through a central pipe 3U leading from the cone if). The heat ot' the llame$- project d t'roin the nozzles if) centers on the cone .29 to rai ie it to a very high temperature. The resultant gas that is thus produced is rendered perman nt by the intrtaiuction of the steam as against. the action oi. cooling and consequently, gas may be conveyed to other heating devices or burners.
